Albert Barnes Commentary Psalms 82:4

"Rescue the poor and needy: Deliver them out of the hand of the wicked." — Psalms 82:4 (ASV)

Deliver the poor and needy - That is, Deliver them from the power and the arts of those who would oppress and wrong them. This would not be showing them partiality; it would be simply doing them justice.

Rid them out of the hand of the wicked - Deliver, or Rescue them from their hands; that is, from their attempts to oppress and wrong them.
